From the graph it can be seen that there is a large fluctuation each year in the. Graph where quantitative data has been collected at different points in time. Time series graphs are important tools in various applications of statistics.

The horizontal axis is used to plot the date or time increments and the vertical axis is used to plot the values of the variable that we are measuring. The graph of time series is called. If this data is plotted onto a graph this will be a time series graph as it shows the frequencies over time.
